The W12x136 is a W-shaped structural steel section listed with dimensional and section data from the AISC 360-16 reference used on this page. The information below is useful for preliminary section identification, drafting, estimating, and coordination before a qualified engineer verifies the member for its intended application.
Use the listed dimensions and properties as the authoritative local reference for this shape. For related terminology, see the site resources on structural steel shapes, section properties, and steel connections and detailing.

refer to : AISC 16
the American Institute of Steel Construction (AISC) Specification for Structural Steel Buildings (AISC 360-16), which is the 2016 edition of the AISC Specification for Structural Steel Buildings. It provides guidelines and requirements for the design, fabrication, and erection of steel structures in the United States.

Unit Weight : 202.1 kg/m
How to read the W12x136 reference data
The dimensional entries describe the principal geometry of the section: overall depth, flange width, web thickness, flange thickness, and root fillet radius. These values help drafters and engineers identify the shape, check clearances, and coordinate the member with connected parts.
Sectional area is a cross-sectional property used in calculations such as axial resistance, self-mass estimation, and related engineering checks. Unit weight is provided as a length-based catalog value. It is useful for material takeoffs and gravity-load estimates, but it should not be treated as a complete design verification.
Using the DWG resource
The downloadable DWG can support CAD coordination and detailing workflows. Before inserting the profile into a project drawing, confirm the drawing units, insertion scale, layer conventions, and whether the file represents the intended orientation. CAD geometry should be checked against the listed reference data and the project’s governing design documents.
Design and detailing context
Section selection depends on more than nominal geometry. Engineers may need to evaluate strength, stability, deflection, connection behavior, fabrication requirements, and applicable project specifications. This page identifies the section; it does not replace a member design, connection design, or review of the complete AISC requirements.
Frequently asked questions
What type of section is W12x136?
It is identified in the source content as a W Beam, a rolled structural steel shape with a web and flanges.
What do the listed dimensions describe?
They describe the section depth, width, web thickness, flange thickness, and root fillet radius. Together, these values help identify the profile and coordinate it in drawings.
What is the difference between sectional area and unit weight?
Sectional area describes the amount of steel in the cross section. Unit weight is a length-based material quantity used for estimating the member’s self-mass and related loads.
Can the DWG file be used directly for fabrication?
The DWG is a CAD reference resource. Confirm its scale, units, geometry, and project requirements before using it for detailing or fabrication documentation.
Does this page provide a complete design check?
No. The listed data supports section identification and preliminary coordination. A qualified engineer must verify the member and its connections for the actual loads, restraints, materials, and governing requirements.
